Hear Every Detail In Stunning Clarity and FidelityWhether you’re building your FLAC file collection or subscribing to a premium music streaming service, you are investing in a higher quality listening experience. Groove unlocks the full potential of that experience, revealing definition, clarity and details like you have never heard before.

Constant Current DriveGroove’s Constant Current Drive output stage dynamically compensates for the nonlinearities – acoustic, mechanical or electrical – of any connected headphones, resulting in lower distortion and a more linear frequency response. Whether listening through earbuds or “hi-fi” headphones, you’ll discover a new level of fidelity, clarity and detail.

Quad Sum DACGroove also features a Quad Sum DAC design which employs four digital-to-analog converters per channel to achieve the highest dynamic range and lowest distortion (THD+N) of any device in its class.

What is a DAC and why is it important?If you’re a music lover and you want the best listening experience, one of the key ingredients in the quality of your sound is the digital-to-analog converter or DAC. A DAC takes the digital information on your computer and translates it into analog sound you can hear through your headphones and speakers.

Not all DACs are created equalYour computer has a DAC built-in, however without a high quality DAC like Groove, you will miss out on much of the subtlety, detail and dimension of music you listen to – regardless of what headphones or speakers you use.
